Product Range / 产品范围

Tees split or combine pipe flow. HEBEI PENGRUN manufactures all standard tee types in carbon, stainless, and alloy steel.

Equal Tee (Straight Tee)

Same size on run and branch. Most common tee configuration. Center-to-end = 1.0 × NPS.

Reducing Tee

Branch smaller than run. Used to combine smaller branch flow into main line.

Barred Tee

Internal bar inside branch to prevent branch pipe from being pushed out by pressure. Common in high-pressure manifolds.

Split Tee

Two halves welded together around an existing pipe. Used for branch connections without cutting the main line.

Lateral Tee (45° Y-Branch)

Branch at 45° angle to main run. Used for combining flows with reduced turbulence.

Cross

Four-way fitting with one inlet and three outlets. Less common; usually two tees are used instead.
